‡0 Authority record control number

Subfield ‡0 (zero) contains the system control number of the related authority record or a standard identifier such as an International Standard Name Identifier (ISNI). The control number or identifier is preceded by the appropriate MARC Organization code (for a related authority record) or the Standard Identifier source code (for a standard identifier scheme), enclosed in parentheses. See MARC Code List for Organizations (http://www.loc.gov/marc/organizations/orgshome.html) for a listing of organization codes and Standard Identifier Source Codes (http://www.loc.gov/standards/sourcelist/standard-identifier.html) for code systems for standard identifiers. Subfield ‡0 is repeatable for different control numbers or identifiers.

Local authority identifiers may be entered in subfield ‡0 locally, but should not be added to master records in WorldCat.

Printing

Field 656 prints as a heading and a tracing. Subfields ‡0, ‡2, and ‡3 do not print. In both the heading and tracing paragraphs, the print program supplies the display constant Occupation: before the subfield ‡a data. Do not enter Occupation: in field 656. In the tracing position, the display constant prints after the appropriate Arabic numeral. The print program supplies a period after the last printing subfield unless final punctuation (. ! ?) is present.
